The invention is a coating blade for coating a paper web and a method of using the same. The coating blade includes a notch in its thickness on the tension side of the blade toward the coating end, above the fulcrum such that it has the advantages of both thick and thin coating blades.

Coating blade and method of using the same

The invention is a method for flocculating clay including the steps of preparing a dispersion of a processed clay containing a polymer as a flocculating agent. The polymer is present in an amount sufficient to cause bridging of particles of the clay in the dispersion by the polymer. Then the dispersion is mixed to cause the polymer to bridge the particles and the particles flocculate. The invention also includes a structured clay produced by this method.

Method for flocculating clay and composition produced thereby

Paper coatings composition containing highly deionized clay or calcium carbonate are disclosed; the compositions provide equivalent rheology at up to 4% higher solids; the compositions provide enhanced glossability; the highly deionized clay and calcium carbonate are also disclosed.
